Remarkable work for the clarity of purpose and the perspectives it offers to perceive, understand and accommodate children / students with another look, another professional posture for teachers in particular. A real discovery for me that the influence or the resurgence of these primitive reflexes or developed in early childhood, and not inhibited by the child / student "who do not keep up." Unlike another opinion of 11/06/12 which states "the end of the book gives only very little of elements on how to really act on those causes," I consider instead that the explanations are very explicit and offer it made numerous courses of action or position (as an educator or teacher): true, then it's case by case, and I do not see how we can offer turnkey solutions. This is the challenge of another book "The domino effect dys" Roselyne Guilloux I found a dangerous contrast to the hands of professional teachers and educators: it is such a condensed symptoms that we want to match specific help or guidance solutions that it becomes unreadable. The risk is especially to see these symptoms in all children / students and detect any disease at all ... dangerous, dangerous at a time when the national education hardly extricate himself from the difficulty she has to meet school difficulties, lack of resources or political will or desire to really understand ... So, there are all specialized companies, which thus become channels of exclusion, all possible profiles of students. The issue appearing to be above all to preserve social peace in the said classes "normal".
